As you can see, Brother Meow has a "sapphire" bracelet on his hand, because many friends think that there will be a lot of iron debris in the car engine, and if the debris is not sucked out, it will wear out the engine. So is this the truth?
Test the process
Brother Meow half a year ago bought a strong magnetic ring hoop on the oil filter core, after the hoop will form a strong magnetic ring, all the magnets can absorb the iron are sucked, we put it on the oil filter element, and then Meow Brother ran for a while, and then the oil filter element was removed to show everyone, in the end this thing has no effect?
Half a year later
Brother Meow has been running on the oil filter element of this magnetic ring hoop for half a year, Brother Meow now put it away first, and then we will cut it open to see if the strong magnetic ring on the hoop is really meaningful.
Brother Meow cut open the oil filter to look at the wall, the circle of iron filings on the wall is actually the iron filings that fell in when cutting, in fact, look at the bottom of the sticky magnet circle, we can see that this circle actually does not have too many iron filings, and then look at the filter paper structure of the oil filter element, because if there is something dirty, it will be attached to the filter paper.
From the current point of view, most of what Brother Meow sees is some iron filings that fall into it when cutting, and the kind of iron filings in the engine are not visible.
That is to say, if there is obviously a lot of iron filings attached, then it should be obvious that there is a circle of iron filings in this circle, but Brother Meow does not see it now.
We look at the bottom again, the bottom does have some flowing black substance, we try it with our hands to see if it is iron filings or the like, Brother Meow twisted it with his hand, there are indeed a lot of black granular, a bit similar to sand, is sludge and other things.
conclusion
Because the suction of the magnet is actually very strong, if there is iron filings, it will be firmly adsorbed on the oil filter element, forming a circle of black debris mixed with sludge, but after Meow Brother cut the oil filter element, it was not adsorbed to the iron filings.
This circle of magnets is consistent with the state of other places, so it is very rational to tell everyone that although metal bracelets are not expensive, they are more of a psychological effect, and they are not as magical as advertised.
Besides, the current engine manufacturing technology is very mature, if there is a lot of iron filings in the oil, then the engine is estimated to be scrapped within 200,000 kilometers.
Therefore, I hope that everyone can look at this matter rationally through Brother Meow's experiment, and I also hope that Brother Meow's experiment can solve your doubts.
